ANATOMY

Detailed explanation-1: -The heart receives deoxygenated blood from the body into the right atrium. This passes from to the right ventricle via the tricuspid valve. The pulmonary artery then carries the blood to the lungs for oxygenation.

Detailed explanation-2: -The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart. From there, the blood flows through the tricuspid valve (TV) into the right ventricle (RV), or the right lower chamber of the heart.

Detailed explanation-3: -So, the correct answer is ‘Pulmonary artery’.

Detailed explanation-4: -Pulmonary Valve-is the semi lunar valve of the heart that lies between the right ventricle and the pulmonary artery-Is in contact with Deoxygenated Blood.

Detailed explanation-5: -Your tricuspid valve opens to let blood travel from your right atrium to your right ventricle. When your right ventricle is full it squeezes, which closes your tricuspid valve and opens your pulmonary valve. Blood flows through your pulmonary artery to your lungs, where it gets oxygen.
